Module has no attribute problem.

[fockez]

I use comtypes within anaconda under win10 64 to talk to ASCOM telescope driver, then I always met the error module 'comtypes.gen.ASCOM_DeviceInterfaces' has no attribute 'ITelescopeV3' I follow the suggestion to clear the gen dir, for the first time I met item 1 in _argtypes_ passes a union by value, which is unsupported then the same. The numpy version is 1.18.1, I want to use comtypes to get numpy array directly from camera driver, without safearray, win32com is too slow for this, I hope comtypes can help.

Thanks.

On an old computer, comtypes 1.1.4 and numpy 1.14.2 on the same windows 10, works fine.

Comfirm the python 3.7.6 cause the problem. Downgrade to 3.7.5 solves it.

#202 similar. 3.7.5 is ok.

This may be caused by a cpython problem.

If the issue remains, please re-open.
